Your computer goes to sleep mid-presentation

Many notebooks are configured to go to sleep or shut off the screen to save energy, but this can interrupt your presentation. To fix it, right-click an open space on the Desktop, click Personalize, click Screen Saver, and then click the Change Power Settings hyperlink at the bottom of the dialog box. Click the radio button adjacent to Balanced, click Change Plan Settings, and then set the Dim The Display, Turn Off The Display, and Put The Computer To Sleep options to Never.

Projector is “out of range”

When you see this message, it usually means that the resolution of your source (typically a notebook or PC) device is too high to display on the projector. Turn the projector off and turn your attention to the PC or notebook. Right-click an empty space on the Desktop and then click Screen Resolution. Click the Resolution drop-down, and drag the slider to match the projector’s native resolution. Click Apply and OK to close the dialog box.

Image fails to appear on the projector

Make sure the requisite cables are connected, the PC or notebook and projector are powered on, and that the projector has had sufficient time to warm up. Set the projector to the proper source by pressing the Source or Input button. Another possible way to pinpoint the problem is to right-click an empty space on the Desktop and then click Screen Resolution. Next, click the Connect To A Projector hyperlink. Your options are Disconnect Projector, Duplicate, Extend, and Projector Only. Click one of the latter three to enable the image on the Projector.

Prevention

The best way to avoid problems is to perform regular maintenance on your projector. Be sure operate your projector within the minimum and maximum temperature and humidity ranges. Excesses can reduce the lifespan of the projector lamp, leading to overheating. Run the projector at less than its peak brightness to extend the lamp life. If your projector supports it, use Eco Mode. Avoid unplugging the projector immediately after the presentation, to give the fan long enough to cool the lamp down.
